A shopping mall is a popular spot where people get their day-to-day necessities. We can observe an immense audience at these malls on holidays and weekends. The cashiers have to put more efforts to complete billing and payment process. Scanning of all purchased products takes long time and generates long queues at cash counters. To overcome this problem, we proposed a smart shopping cart system fixed in a trolley. The trolleys are equipped with barcode scanner and Arduino in it. The products placed in trolleys are automatically scanned by barcode scanners and gets updated in the database. Consequently, it also creates the invoice for the products purchased.
